Beta version 0.4

This release is compatible only with version r36 of the X16 emulator. To hear sound, the emulator still needs to be compiled with the "WITH_YM2151=1" option. For Linux users, it is recommended to modify main.c first to change "AUDIO_SAMPLES" from 4096 to 256 to improve sound timing.

The only noticeable change to the game is the music: the guitar distortion has been reduced to make the theme music less harsh. Under-the-hood changes done include specifying the host file system for loading binaries at run time, meaning that this game is not currently compatible with an SD card, virtual or real, so do not specify a virtual SD card when launching the emulator.
